Harusali is a financial management app for young adults that combines budget tracking with interactive feedback. Users input monthly budgets and track expenses, receiving real-time guidance through an animated coin character. The app calculates daily spending limits, adjusts future budgets based on habits, and uses color-changing backgrounds to discourage overspending. Developed through iterative user testing, Harusali aims to make financial responsibility engaging and accessible, reflected in its high Google Play Store rating post-launch.
